Abstract: A system includes persistent storage containing predefined user interface (UI) component templates and a representation of a web page that includes a runtime UI component configured to reserve an empty portion of the web page to be populated by UI components generated at runtime. The system also includes a processor configured to perform operations, including receiving, from a client device, a request for the web page, and determining, based on the request, that the web page includes the runtime UI component. The operations also include determining runtime parameter values associated with the request, and determining, based on the runtime parameter values and the predefined UI component templates, context-specific UI components to populate the empty portion of the web page. The operations further include generating a context-specific representation of the web page based on the context-specific UI components, and transmitting, to the client device, the context-specific representation.

Abstract: A memory stores a hierarchy representing an arrangement of content for a graphical user interface (GUI), wherein the content includes sibling components that have a common parent component, wherein components of the GUI are respectively associated with position indicators and click counts. One or more processors are configured to: (i) provide a first representation of the GUI with the sibling components arranged according to a first ordering, wherein the first ordering is based on the position indicators of the sibling components; (ii) receive selections of the components, wherein the selections are received by way of the GUI; (iii) update the click counts based on the selections; (iv) recalculate the position indicators based on the click counts; and (v) provide a second representation of the GUI with the sibling components arranged according to a second ordering, wherein the second ordering is based on the position indicators as recalculated.
